How does it run? Does it surge or buck at all. Do you have any exhaust leaks?
No, no surging or bucking, but I kept thinking that it didn't quite have the power it had before, but I'm not sure exactly how to prove that definitely.
I didn't want to push it too much before I knew for sure what the AFR was. And like Novadude mentioned, the gage might be wrong. The problem is that I don't have any other way of testing the exhaust, so I've got to trust (and pray) that it's right.
And no, there's no exhaust leaks either, except for right at the very back end of the pipes, it's awfully loud at that point. But that's mainly due to the "mufflers" that I put on it. They're a pair of Cadillac Northstar resonators, straight through and no packing. Basically the equivalent of galvanized echo chambers, but the back pressure is non-existent. This is one reason why I'm afraid of setting the timing too far ahead, I wouldn't hear it if it pings, the other reason is I'm half deaf now.
I've got to do more testing to make sure I'm not screwing it up by going too lean. And I want to tie the secondaries closed again and see how the primaries perform.
I may have to go back down a jet size or two and drop the rod size, or the other way, only the testing will tell.
On the way up to Tucson, well, down in elevation, up on the map, the AFR was so lean the gage blanked out, but the temperature gages were both showing normal, so I bit my tongue and drove on.
I run a gage off of each head, I don't trust just one gage to catch a problem. That practice has saved me at least one engine, so I keep doing it.
What would increasing the lower idle air bleeds slightly do for it? Would that give it a little more fuel at part throttle? Or do you have to increase the idle tubes to do this?
